Introduction to the Standard
'Family composition' is partly derived from the standard variable 'Relationship in household', which is used to determine family relationships. Other related variables are 'Household composition', 'Relationship between families', Income unit composition', 'Social marital status' and 'Registered marital status'.
The 'Family composition' standard replaced the 'Family type' standard in 2005 and the categories are fully compatible. Correspondence tables are provided in Appendix A of this Standard to support time series comparisons.
